1 claim. (cl. 11a- 109)` The invention relates to a soldering iron atl accommodating nut carrying bolts IIJ so that said tachment and more especially to a vsolder feeding device for soldering irons The primary object of the invention is the provision of a device of this character, wherein the same when carried by a soldering iron will enablethe handling of the latter and the feeding of the solder thereto single handed thus freeing4 the other hand of a user, the device being of novel l@ construction in its entirety and assuring a stepY by ste'p feed of the solder during the use of the iron. I

Another object of the invention is the provision of a device of this character, wherein the w solder is fed to a soldering iron'in a step by step manner t rough the action olla manually controlled .tr gger and a ratchet feed means operated thereby.

A further object of the invention ls the provision of a device of this character,l which is simple in construction, thoroughly reliable and efiicient in operation, readily and easily applied to and r'emoved from a soldering iron and when carried by the latter will assure a perfect feeding of solder to the iron, easy Aof operation, durable,

and inexpensive to manufacture.

, With these and other objects in view, the invenl tion consists inthe features of construction, com` bination and arrangement of parts as will be hereinafter more fully described, illustrated in'v the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claim hereunto appended. J In the accompanying drawing:

Figure 1 is a side elevation of a soldering iron showing the device constructed in accordance with the invention applied. y 't Figure 2 is a fragmentary top plan view of the xdevice. l Y' Figure 3 is a sectionall view taken on the line 3--3 of Figure 1 looking in the direction of the arrows.

f Similar reference characters indicate corre spending parts throughout theJ several views in the drawing. i

Referring to the drawing in detail, A designates generally a soldering iron, in this instance of the electrically heated type, having as usual a pointed tip 5 at one end, a handle 6 at the other end and an intermediate shankl, respectively: the iron being of conventional type.

The,device 'constituting the present invention 'comprises a bracketformed with a relatively long support 8 having integral therewith a double jawed clamp, the jaws being indicated at 9 and clamp can be made fast upon the shank 'I for the mounting of the bracket upon the soldering iron A to have the support 8 spaced therefrom and in parallel relation to the shank. Formed 5 at the foremost end of the support 8 is an outwardly bent hanger terminal II to which is xed a forwardly and inwardly curved feeder tube or spout I2 through which is trained the acid or resin core solder i3 of the conventional strip or 10- tape kind. w

Formed on the support 8 at the rearmost end thereof is an outstanding journal I4 on which is rotatably fitted a spool or windlass I5 having normally wound thereon the solder I3 which in the lli feeding thereof is mechanically unwound from the said spool or windlass.

On the support 8 between the tube or spout I2 and the journal I4 and integral therewith are outwardly directed spaced parallel plate-like 20 bearings I6 between which are arranged closely related rollers I1 and I8, respectively, the former being a guide and the latter a power roller, and accommodating the solder I3 therebetween for the mechanical feeding of such solder by the said 25 `power roller I8. The axle I9 for the roller Il is suitably journaled in the bearings I5 while the axle 20 is also 4suitably journaled in said bearings I6 and outsidevl with respect to said bearings I8 this axle 20 has fixed thereto a ratchet Wheel 2| 30 with which coacts a ratchet dog 22 supported in a substantially U-shaped swinging arm loosely fitted with said axle 28.

The dog 22 has connected thereto a coiled tensioning spring 24 which is suitably connected with 35 the terminal hanger I I and functions to effect ratchet action of the dog 22 in cooperation with v the ratchet wheel 2I so that the power roller I8 will be eiective fora step4 by step feeding of the 4o lsolder I3 through thegtube or spout I2 onto the tip 5 of the iron A. Rearwardly of the arm 23 is a control trigger 25`pivoted at 26 to the support 8 and loosely connected with this trigger 25 is a link 21 which has 45 its end 28 pivoted in the arm 23 and also form. ing the pivot for theidog 22. By operating the trigger 25 the solder I3 will be fed through the tube or spout I2 and unwound from the spool or windlass I5, the feeding of the solder being in a 50 step by step manner through ratchet coaction between the dog 22 and ratchet wheel 2l.

Swin'gingly carried by one of the bearings I8 is a. latching` pawl 29 ccacting with the ratchet wheel 2l to check back movement of the ratchet 55 wheel when the latter through the dog 22 and trigger 2l is operated for the feeding of the solder.

The bearings I. are formed with inwardly struck guide wings or cheeks Il for the solder Il and thus action upon the latter for centering it between the rollers I'I and Il during .feeding thereof.
